To all whom t may concern: n -B'e 'it known'thatll', Fimo'SonUnnnn, citizen of thelnitedfS't'ate's, residin'g'atCleveland, in the county of lCuyz'ihoga and State of! Ohio, have', invented certain'v new7 'and useful A Improvements -inl Self-Closing". Faucets, of which theffllowing'is a specificatifinl` `My invention `a'p'pert'ains to"'selfcjlosing faucet-s, and comprises an! improved organi- 'zatio'nlof parts substantially as 'her'eln shown body, and also involvesthe einp'loyinent of a handlehaving an inset ring ifof good wearing material afliXed lthereto and adapted to afforda Vrotatable baringsurfaee at: the bottom of ,the handle' and a cani'surface within thehandle toseat'the rollers. Other fea- Mtures of` noveltyand ,utility are embodied iu the specific inode of supportingand securingthe valve stein andv handle in operable position within, and ,upon the faucet body,

inthe'means forfasteningthe index member as a crown uponfthe handle, and in lother de- "tailsA of construction as hereinafter more particularly described.

Flg. 7`1s a'sectional view ofthe 'upper earn ineinber, fand preferred' shape 'or style, but Vas shown `it embodies a flanged basef'having a 4'central -valve seat etherein open'to a tubular extensio'n' 5 at its bottoni through which the liquid is adapted to 'flow upwardly. Outiow is throughthespout Gfa't one side ofthe chainbered body 2, and an open'v neck Tof smooth interior and screwethreaded Auponl its veXterio'riprojeots above thebodyin aXi'a'l alinein'eiit'wi'th the valve seat and'is adapted to receive and support 4the vvalve operating parts. .That is to say, a valve'nieinber 8 having a fiber or rubber disk9 aihned to its bottom isy adapted' to rest upon the'valverseat under the press'lue of a strong 'coiled spring l0 sleeved upon the valve stern 1l whichis supported for slidable inovernent lcentrally withinthe body by a packing ring 12 vhaving an' annular .flange llnlafnoped .tightlyl -upon :the upper end face or edge of'neck Trby a unionj nut le. Ring l2 is recessed Vat its top to hold a washer; l5 offibeiginetal or other suitable material and is also'recessed at'its bottoni to hold compressible packing muterial y1G whieh is engaged by a tubular gland or follower' 17 sleeved upon the valve-stern and pressed' upwardly by spring 10. Q The :cii'c'ular'edge'lS off0lloweu`17 is notched at one or niore places tofreceive one or more short'l lugs 19' projecting downward :from

ring y12, and the follower is also provided with onel or more Vslots or `channels 20 with lflaring entrances-21 va'tthe bottoni eudther'eof, whereby one or'lnore lateral projections on the valve 'stein mayy be introduced and have slidable movement i'n the slots or chan- The projections 22 prevent the stein from turning independently of the follower and ring,'and allE of these parts are preveutedjfroni rotating togetlieiwlien the union .nut 14 is screwed tightly in place. '.The di- .A v,vi ded portion of follower 17 is preferably feinforced by a metal band or ferrule 23 having a press lit thereon.

' The length of the valve stein is suchlhat is flat and smooth to serve as a bearing and 4freely in true squared alinement with the valve stem without tilt or upward movement whatsoever and with a permanently n Thus', when ther closed and sanitary joint. parts are adjusted properly spring l0 is under constant tens-ion to press Vthe handle downwardly upon the washer through thek medium of an annular disk 26 slidably keyed upon the upper screw-threaded and channeled extremity of the valve stem, which disk rests upon a series of radially related rollers 27 adapted to ride upon an annular undulating Way or track 28 formed. in the top face of the bottom of the chambered handle. Annular disk 26 is also formed with a corresponding annular undulating way or track 29 at its bottom adapted to ride upon the rollers which revolve on trunnions or shafts carried by a ring separator 30 of any suitable construction, and the disk is looked in place by a flanged nut3l in screw-threaded engagement with the valve stem. The nut is in turn locked in place by radial serrations or teeth 32 retired within a raised border at its bottom and engaged with a plurality of radial teeth 33 in the raised top face of disk'26 which is keyed to the stem by one or more inwardly-extending projections 34, see Figs. 5 to 8. The handle and stem being operatively secured together as described, rotation of the handle in either direction will cause uplift of the stem and raise the valve from its seat, the rollers and undulating surfaces co-acting to bring about this result. Obviously, the wear centers upon the rollers and undulating surfaces, and where the handle is made of cast brass or a similar alloy as commonly practised the greatest wear occurs in the undulating way in that member. To obviate this, I provide rthe handle with an inset member 35 of different metal of good wearing quality Vin the form Vof an annular disk corresponding to disk 26, and as shown the undulating way 28 and the flat seating surface 2st for handle 25 are both embodied in this inset member. In producing this composite handle, an annular seat is formed within the lower end of the round handle body and the member forced thereinvv and finally securely fixed in place in a suitable manner, for example holder 37 by. a screw-ring 39, the diameter -of the ring being large enough to permit nut 3l to Vmove upwardly .tl'iereinwithin thelimit of uplift of the .valve stem. In fact, all the partscarried by the stem withinthe handle must have like freedom of action because the handle merely rotates upon its bot` tom'24 and does not risenor fall with the Vvalve stem as in the usual type of self-closingv faucets known to me.

Also, the cam disk 26 and inset member 35 are preferably stamped or `pressed products and the undulating way on each is prefing an undulating upper surface, a valve having a stem provided with a member having an undulatingbottom surface, rolling members interposed between said surfaces,

Y and a tension device to seat said valve.
